Aside from their technicality which I have read in wiki and other places, why one would choose one over the other?. And why people are excited over supposedly upcoming Fuji camera namely X-A1 which will utilize Bayer array sensor instead of x-trans. Isn't x-trans array that made Fuji IQ 'different' and perhaps now appealing than the rest?

Thanks

X-Trans CFA, being new, is not as well supported by RAW image processing apps, especially the mainstream ones (Lightroom, Capture One, Aperture). A sensor with a bog standard Bayer CFA has decades of optimized demosiacing algorithms available to it, so the files should be easier to process right out of the box.

It comes down to whether you believe Fuji as to the IQ upside of the XTrans CFA, or how much you like using your current image processing tools/workflow, or how much you pixel peep.
